Title: Wave power resonance generator
Inventor: ROWAN DENIS JOSEPH
IPC: F03B13/14
Filed: 1990-06-11
Abstract: A surge of sea water through a guide channel is used to force a column of sea water up inside a chamber in a similar way to a piston in a cylinder. The column of water drives air through a turbine into a second sealed chamber where the air becomes compressed. This compressed air returns through the turbine as the water column falls. The system is tuned (e.g. by varying the capacity of the sealed chamber or the air pressure therein) to resonate with the frequency of sea surges to obtain maximum power conversion efficiency. The turbine may drive an electric generator or an hydraulic pump and the device may be built into a cliff face or installed on a ship. It may be associated with a desalinating plant. <IMAGE>

Patent GB-2244505-A (GB)
Title: Bottom hole blowout preventer
Inventor: LINEHAM DONALD HUGH
IPC: E21B34/00
Filed: 1991-06-19
Abstract: A ball valve type bottom hole blowout preventer (10) operates under normal drilling conditions in a fully open position with an unrestricted bore. This operating condition is maintained by a combination of spring (50, 62) and mud flow pressure acting against the upper surfaces of the valve. In the event of a well kick or blowout pressures from gas or fluid volumes acting against the lower surfaces of the valve force it into the fully closed position. A system of ports and check valves (90) within the blowout preventer forces hydraulic fluid from one chamber (44) to another (66). The metering effect of these ports determines the rate of closure of the valve, thereby allowing normal running and pulling of the drill string or tubing, without interference to pipe fill-up or drainage, from valve closure. This blowout preventer is placed in a sub (94) that is an integral part of the drill string and can be incorporated in a string in any location.

Title: Recovery of gold, silver and platinum group metals with various leachants at low pulp densities
Inventor: BUTLER DEAN ROBERT
IPC: C22B3/24
Filed: 1991-07-29
Abstract: In the recovery of noble metals, including gold, silver and members of the platinum group, the ores or tailings are subjected to the action of various leaching agents, namely, sodium cyanide, thiourea, chlorine and aqua regia and optionally a leaching aid, such as chloride ions. The resulting slurry is then diluted to an optimum pulp density of 0.1 to 10.0% and allowed to stand in a holding tank for periods up to 30 minutes, preferably 15 minutes, with the optional addition of a dispersant, such as sodium silicate, sodium carbonate, trisodium polyphosphate or sodium hexametaphosphate. The pulp is then centrifuged to remove solids if necessaryand is then passed at a pH < 9 through a column containing activated carbon or ion exchange resin/fibre to adsorb any precious metal in solution in the liquor. This is followed by desorption and the cycle repeated as often as warranted by the economics of the process. Alternatively, the pulp is filtered and the filtrate subjected to various recovery techniques, such as cementation, solvent extraction, electrowinning and precipitation.

Patent GB-2259140-A (GB)
Title: Method for data interpolation and signal enhancement
Inventor: PADHI TRILOCHAN
IPC: G01V1/28
Filed: 1992-08-28
Abstract: The method of this invention sequentially determines dips and corresponding estimated dip components of traces in a panel of data. The method can be applied to any data which can be represented as a function of two coordinates. In particular, the method of this invention can be applied to seismic data traces. The method of this invention in one embodiment sums data on traces along a preselected range of trial dips on a panel of data. The energy of the summed data with their corresponding trial dip are then displayed. The dip which has the peak of maximum energy on the display is then selected as a valid dip. An estimated dip component of the selected dip is then determined and subtracted from the traces along the selected dip. The process is then repeated, sequentially, determining a dip and an estimated dip component from the panel of data until the desired number of dips and estimated dip components are determined or the residual energy of the remaining data on the traces are below a preselected value. After the dips and estimated dip components are determined from the panel of data, the information can then be used to place an interpolated trace within the panel of data, to create a new panel of data having uniform spacing between the traces if the original panel of data had some non-uniform spacing, and/or to enhance the traces by creating a new panel of data having only the determined dips and estimated dip components thereby removing from the data panel randomly distributed noise.
